Iowa Nutrient Reduction Strategies
The Iowa League of Cities began a project to create the Nutrient Reduction Exchange (NRE) to enable municipalities and other NPDES permit holders to meet their nutrient reduction obligations through work in watersheds and with other non-point source partners.
The Iowa Nutrient Reduction Strategy is a science and technology-based framework to assess and reduce nutrients to Iowa waters and the Gulf of Mexico. It is designed to direct efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable and cost effective manner.
Working together, the Iowa Department of Agriculture and Land Stewardship, the Iowa Department of Natural Resources, and the Iowa State University College of Agriculture and Life Sciences developed this proposed strategy.
The Iowa strategy outlines a pragmatic approach for reducing nutrient loads discharged from the state’s largest wastewater treatment plants, in combination with targeted practices designed to reduce loads from nonpoint sources such as farm fields. This is the first time such an integrated approach involving both point sources and nonpoint sources has been attempted.
